Abstract

The flow dynamics in the tip-top region of hydraulic turbomachines were investigated using large-eddy simulation (LES). LES explictly computes a range of energetic flow scales, and it only models the flow scales smaller than the computational cell size. The spatially filtered, 3D, unsteady and incompressible Navier-Stokes equations were solved in conjuction with Lagrangian dynamic subgrid-scale (SGS) model. It was observed that sufficient resolution are allocated near the blade surface and within the tip gap.
